SPECIFICATION forming part-of Letters Patent No. 781,522, dated January 31, 1905.

Application filed January 30, 1904. Serial No. 191,266. I

To whom it l] 00771087! intervals with recesses, as at e, to receive the Be it known that I, FRANK I). HOWE, a citiheads of the fastening-bolts. Zen of the United States, residingin Richmond Surrounded by th'e cap ,0 and held between 5 Hill, in the county of Queens and State of New said cap and the wheel-hub is a thrust-collar York, have invented certain new and useful f. This collar engages the axle by resting Improvements in Wheels, of which the folfreely in a circular groove g, provided in the lowing is a specification, reference being had axle, and is preferably clamped tightly bev to the accompanyingdrawings, forming apart tween'a flange it within the cap and the end 55 hereof. 0f the wheel-hub, so that as the wheel-hub I One of the objects of the present invention revolves about the axle the .collar turns in the is to provide improved means for fastening groove. It is-immaterial, however, whether wheels upon the axles of vehicles. In many the collar revolves with the wheel or not, for, instances it is desirable that such fastening if desired, said collar may have a tight [it 60 means be inclosed, partly for the reason that within the groove g, while its working faces the axle and the fastening means are thus proare next to the cap and wheel-hub. In order, tected from collisions with other objects and to place the collar in the groove around the from dust .and dirt which ordinarily collects axle, it may be split, although it will be obaround the end of an exposed axle and also vious that the end in of the axle may be made 5 because the fastening means are in this way in a separate piece. In the latter case the made safe from the interference of ignorant collar f may be a complete ring fitted upon or careless persons who sometimes tighten up the end of the axle, towhich the head it is afthe fastening devices against the wheels and terward secured. It will be clear also that render the turning of the wheels diflicult. the collar f and head is may, if desired, be 7 Another object of the invention is to promade'in one piece. 5 vide means for preventing the oil upon the In order to keep the lubricating-oil from working surface of the axle from leaking out leaking out from the-working surfaces of the around the endofthe wheel,an d thereby smearaxles and smearing the adjacent portions of ing the adjacent parts of the wheel and of the the vehicle, the end of the wheel hub next to 75 vehicle to which the wheel'is attached. the vehicle is provided with a circular groove 3 Still another object of the invention. is'to extending around the axle, Fig. 2, in which provide an improved means of lubricating the there is provided a packing-ring Z, which is axle. caused by the force of a spring m to press In the drawings, Figure 1 is aview' in cenwoutwardly against the flange n upon and 80 tral section of a wheel-hub and of the axle around the axle. Between the spring and upon which it is journaled, showing particua packing-ring there is" preferably a washer r, larly the means for fastening the wheel to the of leather or some suitable material, to form axle; and Fig. 2 is a view, partly in elevation an oil-tight joint. In this way theoil is efand partly in section, upon a larger scale, fectively confined to the working surfaces for 35 showing a portion of the wheel-hub and axle which it is intended. In order to prevent 4 and illustrating the means for preventing the any oilwhich happens to work past the packoil from Working out around the end of the ing-ring Z from escaping and also to protect Wheel. Y the working surface of the axle from dust The wheel a, journaled upon axle .7), has a and dirt, a flat ringo is secured to the flange 9 cap 0, which is rigidly securedthereto by suita, and the wheel is provided with a broad able fastening devices, such as bolts, one of flangep, overlapping the ring 0, as clearly which is shown at d. The exterior of the cap shown in Fig. 2. I is preferably rounded and provided at proper To provide lubricant for the working surfaces of the Wheel and axle, the cap 0 is made hollow and is filled With oil. This oil Works back and forth around the collar f and over the Working surfaces of the axle and Wheel and is prevented from escaping at the other end of the Wheel-hub by the packing-ring Z, just described.

I claim as my invention 1. The combination of an axle having on its outer end an annular groove, a Wheel-hub on the axle, a split collar arranged in the groove of the axle against the outer end of the hub, and a cap removably secured against the outer face of the hub, having an internal flange bearing against the outer face of the split collar.

2. The combination of an axle having on its outer end an annular groove, a Wheel-hub on the axle, a split collar arranged in the groove of the axle against the outer end of the hub, and a cap having recesses formed in its outer face, bolts having their heads in said recesses and extending into the outer end of the wheelhub to hold the cap against its outer face, the cap having an internal flange bearingagainst the outer face of the split collar.

3. The combination of an axle, a Wheel-huh thereon having in its inner end two annular concentric grooves, a flange on the axle hearing against the inner end of the hub and closing the inner groove of the hub and having secured thereto a ring extending into the outer groove of the hub, a metallic packingring in the inner groove, a spring in the inner groove holding the packing-ring against the flange of the axle, and a non-metallic washer between the packing-ring and the spring.

This specification signed and witnessed this 28th day of January, A. D. 1904..
